Abstract (en)
Disclosed is a speaker bearing array sound-conducting structure, disposed in a headphone. The structure comprises: a plurality of speaker units provided in a front cavity of the headphone; a bearing disposed in the center of the plurality of speaker units, such that the plurality of speaker units are uniformly distributed around the bearing centered about the bearing on the same layer, so as to generate a middle channel that produces sound; a sound output opening disposed in the front cavity, so as to fix the plurality of speaker units, and to concentrate the sound in the bearing and then conduct the sound outward; and a baffle disposed behind the bearing, so as to control a conducting direction of the sound. Also disclosed is a headphone made from the speaker bearing array sound-conducting structure. Because the speaker bearing array sound-conducting structure of the present invention uses a special bearing array arrangement approach, the transmission channels of speaker units are created and controlled, so as to achieve the highest sound transmission efficiency and the best sound synchronization performance.
